BOTTLE AND THE LIKE.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed March 26, 1907. Serial No. 364,600.

To all whom it may concern.-

Be it known that we, THOMAS WALTERs, asubject of the King of Great Britain and Ireland, &c., residing at Bowen Terrace, Brisbane, in the State of Queensland, Commonwealth of Australia, and JOIIN BALLANTYNE HENDERSON, a subject of the King of Great Britain and Ireland, &c., residing at Mary street, Brisbane, in the State of Queensland, Commonwealth of Australia aforesaid, have invented certain new and useful Improvements in Bottles and the Like to Enable Opening and Prevent Fraudulent Refilling; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This inventionis to provide improvements in bottle devices and the like, with the objects of enabling the bottle to be rapidly and'easily opened, and once opened to be unfit for refilling with fraudulent intent. Various inventions which have such objects are complicated and unsightly. In some there is provision for breaking off the bottle neck or part of it; but with liability to leave an irregular or jagged edge of glass which would be dangerous.

The direct objects of this invention are to avoid that disadvantage and to secure others.

In carrying this invention into effect a special form of bottle neck is provided, and, in addition to any ordinary cork or stopper, one or more parts are used, as below described, to constitute a seal.

In the drawings herewith Figure 1 represents on an enlarged scale an elevation of part of a corked and sealed bottle and Fig. 2 is a sectional view of a modified form.

The drawings show the bottle neck A shaped inside in any manner suitable for the reception of a cork or stopper B; but with the addition of two grooves. The upper of these grooves, marked 0 is near the top or rim D of the neck, the internal diameter at E of which above groove C is greater than that at F, of the said neck. The cork is to be driven in at least partially below groove 0, ordinarily with the cork top as shown, a

slight distance above the groove lower edge. The second internal neck groove is a narrow one A lower down than groove C but not lower than the part the cork fills when inserted. In the bottleneck over the cork is placed a sealing device having a top consisting of a disk of tin-plate, steel, or suitable metal G of such form as to be expansible in diameter under pressure. Before it is inserted it may be convex with any suitable edges. This disk or member is changed into a practically flat (or a concave) one by the force applied in sealing, the disk edges being so far driven out or expanded into groove 0 that its diameter is greater than the diameter E. When the metal of the disk G is sufficiently yielding and pressure is suitably applied the expansion aforesaid may be effected without using an additional or guide plate which however is used in ordinary cases. This guide plate is placed on the cork and consists of a hard steel or rigid metal disk H which may be fiat or have its upper surface of concave, convex, or other suitable form with its rim located to act as a guide as described below. Its diameter is in some cases greater than the diameter at level F of the bottle neck; it proj ects in such cases beyond the cork, as at H but with out being of so large a diameter that it cannot be easily dropped into place. Member I-I being under member 1 G acts as a guide so that when pressure is applied on top of disk G the latter may expand as in Fig. 1. When expanded it presses into a ring M of rubber, or wax, or cementing material inserted in groove 0.

With the combination of parts described the seal cannot be removed without breaking the glass; and the cork is held in in spite of gaseous pressure below it,wiring thus being unnecessary.

Outside the bottle neck is a shoulder .T which extends laterally beyond the part K of the neck below it. A sufficiently direct upward blow (as along the latter part of the neck or per arrow in Fig. 1) on the under side of shoulder J will break the neck clean around as undermentioned.

At the foot of shoulder J is a groove L round the neck to thin the glass outside opposite where it is thinned inside by the grove A so that it shall be there broken with certainty when the blow aforesaid is struck. The outer groove is also provided to be used as a guide for a cutting appliance when the use of the latter is preferred. The neck top is to break all round at its thinnest part between the inner and outer grooves. The metal disk G owing to the alteration of its shape during insertion is not suitable for reuse after it has been expanded. It would bear in ordinary cases a distinguishing indication determined on by the proprietor of the liquid or substance bottled or packed. When the disk G is expanded into the groove the pressure on the disk may form a slight depression in the top of the cork and disk H and make the cork tighter. Disk G in some cases is centrally perforated as at G Fig. 1 to allow of the forcing out of the disk from the I as pliers may be used provided internally with glass cutters by rotating which the cutters must scratch into the groove all round. As will be seen groove A is shown a little lower than groove L and, it the glass cracksas intended in a line which (from outside to inside) is slightly inclined downwardlythe liquid can be poured out neatly: there will be no sharp inner glass edge to cut any cork that may be inserted to preserve the liquid in the bottle in cases in which the said liquid is drawn upon at intervals.

The invention is not however limited to the precise designs and details illustrated; and it is applicable not only to vessels of glass, but also those of other brittle material as porcelain or earthenware.

What we'do claim as our invention and desire to se cure by Letters Patent of the United States is:

1. In combination, an internally and externally grooved vessel neck of brittle material, a cork, a sealing disk, a guiding plate disposed between said sealing disk and said cork, and cementing material adapted to hold said sealing disk, substantially as described.

2. In combination, an internally and externally grooved vessel neck of brittle material, a cork, a sealing disk, a guiding plate having a flared rim disposed between said sealing disk and said cork, and cementing material adapted to hold said sealing disk, substantially as described.

In combination, an internally and externally grooved vessel neck of brittle material, a cork, a perforated metallic expanded sealing disk, a guiding plate having a flared rim disposed between said sealing disk and said cork, and cementing material adapted to hold said sealing disk, substantially as described.

l. A bottle or vessel neck of brittle material, having therein a cork or stopper, a guide plate upon it, an expanded disk upon the guide plate, the neck having oppo sitely set inner and outer grooves, and an upper inner groove and a sealing medium disposed around said upper groove and engaged by the peripheral edge of said disk, substantially as described,

In witness whereof we have hereunto set our hands in the presence of two witnesses.
